Abstract
The time-resolved PSL studies of CsBr1−xClx:Eu2+ system has been studied for different europium concentrations. An efficient PSL material for use in image plate should have very short PSL emission lifetime. PSL emission lifetime for stimulation at 650 and 630 nm (F(Br−)- and F(Cl−)-centers) for CsBrCl:Eu2+ is determined to be 0.69 μs. The lifetime of BaFBr:Eu2+, the commercially available image screen phosphor is 0.8 μs. The present observation support the use of CsBrCl:Eu2+ as an efficient X-ray image screen phosphor.
